本文介绍了安卓：有没有办法从Location.getAltitude一边得到高度（）？（我用传感器听说过）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

有没有办法从Location.getAltitude一边得到高度（）？我听说使用传感器，但没有思想，不能找到网。

Is there a way to obtain altitude aside from Location.getAltitude()?I've heard using Sensor but don't have idea and can't find on net.

UPDATES1 我发现 SensorManager.getAltitude（浮动，浮动）使用API 9级了，但没有想法就如何落实它。你会与我们分享。

UPDATES1I found SensorManager.getAltitude(float, float) using API Level 9 up but don't have idea on how to implement it. Would you share with us.

推荐答案

我知道它的晚，但任何人都在寻找它，这可能有助于

I know it's late but for anyone looking for it, that might help

import android.app.Activity;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;
import android.os.Bundle;

public class MyActivity extends Activity implements SensorEventListener {

    private SensorManager sensorManager;
    private Sensor sensor;
    private float altitude = 0;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        sensor = sensorManager.getDefaultSensor(Sensor.TYPE_PRESSURE);
    }

    @Override
    protected void onResume() {
        super.onResume();

        if (sensor != null)
            sensorManager.registerListener(this, sensor, SensorManager.SENSOR_DELAY_NORMAL);
    }

    @Override
    protected void onPause() {
        super.onPause();
        sensorManager.unregisterListener(this);
    }

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {}

    @Override
    public void onSensorChanged(SensorEvent event) {
        float presure = event.values[0];
        altitude = SensorManager.getAltitude(SensorManager.PRESSURE_STANDARD_ATMOSPHERE, presure);

        System.out.println("altitude => " + altitude);
    }
}
